E18 Koskenkylä–Kotka motorway opened for traffic In Finland

The new motorway from Koskenkylä to Kotka was opened for traffic on Monday, September 1, 2014. Spanning a total of nearly 53 kilometers, the motorway construction was divided into 6 sections, of which the Loviisa–Ruotsinpyhdäs and Ruotsinpyndäs–Ahvenkoski sections were opened for traffic on Monday. The construction started in November 2011. Parts of the motorway were opened for traffic already in 2013, and the opening of the final sections on September 1, 2014, complete the project.

The project is implemented under a life cycle agreement extending to 2026 by Tieyhtiö Valtatie 7 Oy, and the contractor was the consortium Pulteri formed by YIT Construction and Destia. The project won the Construction Site of the Year award from Rakennuslehti magazine.

Project Manager Kari Alavillamo describes the scope of the project:

“Apart from bridge construction, the project also involved very extensive earth construction: a total of some 3.5 million cubic meters, i.e. 700,000 truck loads of excavated soil plus 4.4 million cubic meters, i.e. 590,000 truck loads of transferred soil masses. More than 3,700 people were trained to work at the site and at its highest, the work force strength was 750.”

Transport telematics for the Porvoo–Kotka section were also inaugurated on Monday. Telematics are used for monitoring traffic volumes, speeds and local conditions, and remotely controlled traffic signs and info boards will be controlled on the basis of this information.
